You multiply the numbers just like you would normally except that the product will have a negative sign. Example: -6 X 5 = -30. When you multiply a negative number and a positive number, the product will always be negative. Multiplying two positive numbers or two negative numbers will give you positive products.

A positive number times another positive number will give you a positive answer. If you multiply two negative numbers together, you will also have a positive answer. The only way to get a negative answer is if you multiply a positive by a negative.
